BALlNG-PRESS.

'.:PECIFIGATION forming-part of Letters Patent No. 719,278, datedJanuary 27, 1903. Application filed May 5,1902. Serial No. 105,877. (Nomodel.)

To @ZZ whom t may con/cern:

Be it known that 1, J OSIAH S. TUrTLE,acti zen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in BalingPi'esses,ofwhich the following is a specification.

My invention relates to baling-presses, and more especially to that typeprovided with ro attachments for automatically forcing the charge ofbaling material from the hopper into the baling-chamber; and my objectis to produce a machine of this character which operates efficiently andis of simple, strong, and durable construction.

To this end the invention consists in certain novel and peculiar'features of construction and combinations of parts, as hereinafterdescribed and claimed, and in order that it zo may be fully understoodreference is to be had to the accompanying drawings, in which-- Figure 1is a horizontal section taken through the power-shaft and a portion ofthe baling-case of a baling-press embodying my z 5 invention Fig. 2 is across-section taken on the line II II of Fig. 1. Fig. 3 is across-section taken on the line III III of Fig. 1.

In the said drawings, 1 designates the baling-case of any suitable orpreferred type and 3o provided with a feed-opening 2 in its side bypreference and afquadrant-shaped hopper 3,

communicating with said opening and by preference arranged horizontallyand adapted to receive the charge at its outer end instead of at itsupper end.

fl designates the usual orany preferred bedplate connecting thebaling-chamber with a metallic frame 5, in which the vertical powershaft 6 is journaled, said power-shaft carry- 4o ing the trip-lever,composed in this instance of two arms 7, equipped withantifrictionrollers 8 at their outer ends and adapted for successiveengagement with the plungerbeam 9. This plunger-beam, as usual, isprovided with a pocket 10 at its front end and is attached at its rearend in the usual manner to the plunger 11 for operation in thebaling-case, said plunger being provided with rearwardly-projecting sidearms 12, which 5o bridge the opening 2 when the plunger has completedits in or power stroke, so as to prevent the material being baled fromgetting behind the plunger.

Pivotally connected to frame 5, as at 13, at the opposite side of theplunger-beam from the power-shaft is a cam 14, said cam occupying thesame plane as the plunger-beam and having its periphery growinggradually more remote from its aXis from its front end or point 15 toits rear end or point 16, and 6o pivotally connecting said cam at ornear point 16 to the front end of the plunger-beam is a link 17, saidlink for strength and stability being composed of two parts, one belowand the other above the cam and plunger-beam, as shown.

In the practical operation of the mechanism described it will beunderstood by reference to Fig. 1 that when the plunger is withdrawn topermit a new charge tobe forced 7o into the baling-chamber the front endof the plunger-beam is projecting a distance beyond the power-shaftsubstantially equal to the length of link 17 and that in consequence thepoint 16 of the cam is approximately in 75 alinement with power-shaft 6and pivotal point 13 and the plunger-beam is in contact with theperiphery of the cam.

While the plunger-beam is in the position described, an arm of thetrip-lever strikes it 8o while traveling in the direction indicated bythe contiguous arrow. This outward pressure on the plunger-beam, owingto the fact that the pivotal point of connection between the latter andthe link is rearward of the verti- 8 5 cal plane of the pivotal point13, and the antifriction-roller of said trip-lever arm causes the cam toswing in the direction indicated by the contiguous arrow and through themedium of link 17 pull the plunger-beam at acorrespond- 9o ing speedinthe direction indicated by its contiguous arrow, the contact between thecam and theiplunger-beam engenderin g practically no friction because itis a rolling contact or connection. The initial partof the movement ofthe plunger-beam is thus effected with great rapidity and smallexpenditure of power.

By the time the material has been suficiently compressed to oder heavyresistance the function of the cam is ended and the roller of the 10ctrip-arm has entered the pocket of the plungerbeam and remains in suchposition until the instroke of the plunger is completed, thedisengagement of the trip-lever and plungerbeam being insured by thestop-arm 18, arresting the plunger-beam when it attains the positionshown in full lines, Fig. 1, and in this connection it will be noticedthat the front end of the plunger-beam is sustained in a horizontalposition by the shelf or bracket 19, secured to the bed-plate.

20 designates a vertical shaft arranged axially of the hopper 3, andjournaled in suitable bearings secured to the baling-chamber andprojecting from said shaft and into the hopper, through the slots 2lthereof, is a feeder composed of one or more arms 22, the outer ends ofsaid arms being formed with substantially V-shaped teeth 23 andconnected by a presser-plate 24:, the function of the latter being toforce the material from the hopper through the feed-opening 2 into thebalingchamber, while the toothed ends of the arms are for the purpose ofmore effectually tucking such material into the baling-chamber.

Upon the upper end of shaft 20 and overhauging the baling-chamber is anarm 25, connected by a retractile spring 26 to a fixed `point on thebaling-case, this spring normally holding the feeder Withdrawn, as shownin full lines, Fig. 1.

27 designates a peripherally-grooved drumsegment mounted rigidly onshaft 20 and projecting into the baling-chamber, the plunger having agroove 28 in its side to receive said drum, so that there shall be noconflict between the segment and the plunger.

29 designates a chain or cable which engages the grooved periphery ofthe segment and is secured rigidly to the outer end of the latter, andsaid chain or cable extends around and forward of a pulley 30, mountedon the bed-plate below the plunger-beam, the opposite end of the chainor cable being swiveled or otherwise attached to the angle-lever 31,pivotally mounted at its front end, as at 32, on vframe 5, saidangle-lever being provided with a shoulder having a cam or inclined face33, a short face 34, adapted to extend about concentrically of thepower-shaft at times, and an inclined face 35, the face 34E connectingfaces 33 and 35.

YWhen the plunger has completed its instroke and the trip-lever arm isabout to pass from engagement with the plunger-beam, the spring 26 holdsthe feeder withdrawn and the angle-lever, with the cam, contiguous toand in the path of movement of said trip-arm. As the latter releases theplunger-beam it recoils to its initial position, being guided in suchreturn by the cam and link. As the plunger-beam recoil takes place saidtrip-lever arm strikes said angle-lever and rides upwardly upon theinclined face 33 thereof. Said lever4 is then forced outwardly andthrough the medium of the connecting-cable swings the feeder inwardly,spring 26 yielding to accommodate such movement. By the time saidtrip-lever arm has passed into engagement with face 34 the feeder hasforced all of the material from the hopper into the baling-chamber and'completely closes the feed-opening 2 and has its toothed ends projectinginto the baling-chamber.

During the short period of engagement of the trip-lever arm with thecam-face 34- the feeder occupies and closes opening 2, and the oppositearm of the trip-lever has engaged the plunger-beam and forced theplunger from its initial positionalmost to the toothed end of thefeeder-that is, until it has traveled almost clear across thefeed-opening. As the plunger attains a position contiguous to saidtoothed end of the'feeder the firstnamed trip-arm clears cam-face 34 toenable the spring 26 to instantly withdraw the feeder from the path ofthe plunger,said first-named trip-arm riding down upon cam-face 35 ofthe angle-lever as the latter swings inward. The power portion of thestroke now commences and during its progress the operator is rechargingthe hopper, the arms 12 of the plunger preventing the recharge fromgetting into the baling-chamber and interfering with the proper actionofthe plunger.

As all subsequent operations are repetitions of those described, it willbe apparent that I have produced a baling-press which embodies thefeatures of advantage enumerated as desirable in the statement ofinvention and by which material maybe automatically forced into thebaling-chamber without possibility of coniiict between the baling andfeeding mechanisms, and while I have illustrated and described thepreferred embodiment of the invention it is to be understood that it. issusceptible of modification in various particulars Without departingfrom the principle and scope or sacricing any of its advantages.
